PATENT oFFics 1 Claim.

The present invention relates to steam fittings and has particular reference to a convertible union or the like serving in the capacity of an attachment for hot water, steam or the like radiators for connecting the supply and return pipes of the heating system with the radiator.

The primary object of the invention is-to provide a simple and efficient fitting of the. class described which is so constructed that it may be employed on the right or left hand side of the radiator by the simpleexpedient of reversing its position thus obviating the necessity of making separate right and left hand fittings for this pur- The application of the preferred form of the invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a view'in side elevation showing the fitting contemplated by the invention accommodating the supply and return pipes on the left hand side of the radiator; V

Fig. 2 is a top plan view showing the inter- V changeable or convertible possibilities of the fittime;

Fig. 3 is a detail view in cross section of the fitting;

Fig. 4 is a view in cross section taken on the line 4-4 of Fig. 3, and

Fig. 5 is a fragmentary end view of the radiator showing the application of the fitting thereto.

Referring now to the drawing in detail A represents a steam, hot water or the like radiator, comprising a plurality of assembled sections of ordinary construction. At the top of the radiator is located the valved intake 5 to which is connected pipe section 6 of the supply.

' 1 representsthe fitting contemplated by the invention the same preferably comprising a cast unitary structure fashioned with integrally formed non-communicating supply and return passages 8 and 9 respectively, all of which being internally or externally threaded at their outwardly offset extremities to accommodate the pipes immediately leading to and from the radia: tor. As an assembly the pipe 6 is received in the internally threaded opening I0 of the supply passage 8 directly opposite internally threaded opening II which receives the supply pipe 6a of the circulating system. As will be clearly shown from Fig. 4, the pipe sections 6 and 6a are-attached to the fitting to establish a communication through the passage 8, so that water, steam or other heating fiuid may be supplied to the top of the radiator. The return passage 9 as previously stated is cast as an integral part of the fitting but in no way communicates with the passage 8. This passage 9 is fashioned as an elbow disposed transversely of the passage 8, it has an externally threaded intake I2 and an internally threaded outlet I3. The inlet I2 has a ground joint I6 and a union, I1 is adapted for connection with a short length of pipe I4 from the bottom of the radiator and the outlet I3 is adapted for connection with the return pipe I5 of the circulating system. It is of course understood that the connections I0,

'II, I2 and I3 may be internally or externally turn also accommodated through the fitting and with the passages through the fitting for the supply and return separately formed and in no way communicating one. with the other.

As previously stated one of the outstanding features of the invention resides in the advantages to be gained by providing a supply and return fitting which may be used in either the right hand or the left hand side of the radiator without employing accessory fittings or in any other way disturbing the original construction of the fitting.

As viewed from the drawing when the fitting is used on the left hand side of the radiator the connection I2 is connected to the short pipe section I4- and the connection I3 is connected to the return pipe I5 whereas when the fitting is used on the right hand side of the radiator viewed from the drawing the position of the connections l2 and I3 is just reversed in that the connection I3 is connected to the short pipe section I4 and the connection I2 is connected to the return pipe I5. This is the only change that takes place.

By making a fitting in accordance with this invention a great saving is realized in production cost since it will not only obviate the necessity of making right and left hand patterns, but it will also remove the necessity of carrying a quantity of right and left hand fittings in stock.

Aside from these advantages attention is also called to the design of the fitting which makes it neat in appearance, easy to cast without exercising skill in its fabrication.

Having thus described and shown an embodiment of my invention, what I claim and desire to secure by Letters Patent of the United States,'is:

In combination with a radiator having duplicate end sections, each provided with an upper inlet and a lower outlet opening, of a reversible fitting adapted to be secured to the lower outlet opening of either end section of said radiator, said fitting being formed with a vertical passageway having top and bottom pipe connections establishing communication with the upper inlet portion of the radiator, and an elbow cast integrally with said fitting and having an entirely separate and continuous passageway therein disposed in FRANK P.
